Preferably, the height between detecting electrode portion 22 and electret electrode section 23 can adjust as required, thus makes the space of sense channel 24 have adjustability.
Thin slice pick-up unit in the present invention also comprises mounting casing, and thickness detecting sensor 20 and import guidance part 30 are all arranged on mounting casing.
Preferably, detecting electrode portion 22 is transparent.Because detecting electrode portion 22 is transparent, when being thus provided with imageing sensor 10 below thickness detecting sensor 20, thickness detecting sensor 20 effectively can being avoided to block object to be detected, thus ensure that the functional reliability of imageing sensor 10.

During image read-out work, first object to be detected by passing through import guiding channel, the first guide plate 33a and side, detecting electrode portion 22 is more pressed close to make object to be detected, enter in sense channel 24 by middle guiding channel 33c, detected by imageing sensor 10 and thickness detecting sensor 20 to make object to be detected, the induced charge on detecting electrode 22c can be made to change when the thickness of object to be detected changes, the variable quantity of induced charge is relevant with the change size of detected material body thickness, the signal that detecting electrode 22c exports obtains the thickness change information of object to be detected after the process of testing circuit 70 and subsequent conditioning circuit, simultaneously, the light source 12 of imageing sensor 10 is luminous, light beam is irradiated on the object to be detected in sense channel 24 by light-passing board 15, collected by lens 17 through light-passing board 15 again after being reflected by object to be detected, be irradiated on the photographic department 13 on substrate 14, photographic department 13 converts the light signal received to electric signal, the image information of object to be detected is obtained after the analyzing and processing of subsequent conditioning circuit, by successive image treating apparatus and display device, the thickness change information of object to be detected and image information are combined, finally obtain the details such as position and characteristics of image of object to be detected variation in thickness, object to be detected after having surveyed is transported output by the second outlet guiding channel, the first outlet guiding channel successively.
Image read-out in the present invention also have rational in infrastructure, easy and simple to handle, volume is little, be easy to carry, the feature such as production cost is low, applied range (can be widely used in finance device field).
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
